Too anxious about jobs

I don’t know if anyone has this problem but I’m too anxious when it comes to jobs, I studied a degree but was too anxious when it came to the internship to actually do the role so left that career. I’m too scared of making a mistake, not being good enough. I’ve tried admin jobs, hospitality and left in 3months or a year after. I have gaps in my resume and have been unemployed much longer than employed due to my mental health. I just don’t know what to do anymore and I feel less than everyone else and not capable to do anything at all
